Thanks, fixed that!

@loretoparisi can you modify it per below? (remove the <a> tags in the second <td>):

script = document.createElement('script');script.src = "https://ajax.googleapis.com/ajax/libs/jquery/1.6.3/jquery.min.js";document.getElementsByTagName('head')[0].appendChild(script);
function download(name,jsonObject) {
    var fileContents = JSON.stringify(jsonObject, null, 2);
    var pp = document.createElement('a');
    pp.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(fileContents));
    pp.setAttribute('download', name+'.json');
    pp.click();
}
df={}
$( $('.wikitable')[0] ).find('tr').each((index,item) => {
    if(index==0) return
    cntrc=$($(item).find('td')[0]).text().replace(/\n|\[.+\]|\(.+\)/g,'').replace(/\s+/g, ' ').replace(/^\s+|\s+$/g, '')
    // remove links in expanded words
    $($(item).find('td')[1]).find('a').remove();
    // return the first match in the expansion and return the first comma separated value
    // (this accounts for Scottish <a> and "'s" mapping to "is, has, does, or us" vs. just "is"
    expnd=$($(item).find('td')[1]).text().replace(/\n|\[.+\]|\(.+\)/g,'').replace(/\s+/g, ' ').replace(/^\s+|\s+$/g, '').split('/')[0].trim().split(',')[0].trim();
    df[cntrc]=expnd
})
